Since the mobile era, touch screens have been at the core of our user interface with electronic devices. However, as the technology behind touch interfaces begins to saturate, many players now look beyond touch to the future of user interfaces. Whilst advanced solutions including voice and gesture detection, right through to perceptive computing are suggested, many suppliers are looking for the best ways to improve the existing platform. It is possible to literally add an additional dimension to touch interfaces by adding force sensing. This trend has been strongly visible from various market leaders throughout 2015 and 2016, according to a new report by market research firm IDTechEx.
However, force sensors themselves are certainly nothing new, and even their use within user interfaces dates back over 40 years where they were first used in musical instrument toys. In fact, force sensors in musical instruments including electronic drum kits, keyboards and more has been the most mature market, and until 2015, one of the largest (when focusing specifically on user interfaces at least). However, with many high-profile consumer electronics products containing force sensing interfaces launched throughout 2015 (most notably from Apple, in their smartwatch, laptop and smartphone products), this has quickly dominated the market. As such, the user interface landscape is undergoing a period of significant change, with force sensing as a prominent early step.
The report expects capacitive force sensing to remain dominant, with advantages over resistive options and immaturity in more emerging techniques such as piezoelectric polymers or dielectric elastomers allowing them to dominate the market. The report also covers detailed application ideas across sectors including consumer electronics, automotive and industrial markets. This includes well characterised products like the smartphone or tablet, through to important future markets like controllers for AR & VR devices, and also smaller niches like musical instruments and home appliances & tools.
Whilst force sensing is certainly not the user interface end game, it represents a very important step as the entire value chain behind user interfaces moves beyond touch. The value proposition is initially subtle, with many interesting features as detailed within the report but a distinct lack of any 'killer-app' within the consumer space for now. However, as technology and markets mature, we expect that areas such as input controllers for VR and AR devices (building on an initial base from the games console controller space) and later as a user interfaces in the automotive spaces will drive growth to around $1.8bn in annual force sensor sales for user interfaces alone.
